To me you have that backwards. Kelvin wouldn't act on HIS own without the AD's consent. I don't know how it works exactly, but I'm guessing any paperwork filled out is usually filled out by the AD, not the coach. Certainly the coach isn't making decisions like that with without the okay of the AD.
I just don't see it. Kelvin didn't really know the kid. The AD on the other hand, did. If Kelvin wanted to fight it, and the AD didn't, it wouldn't have been fought. And we don't have any evidence that it even is being fought. Transfers are required to sit out. The transfer has to come up with the reason for an exception to be made. That isn't on Kelvin or the Houston AD.
Yes they are required to sit out but it hasn't been the norm recently especially with coaching changes. I promise you no AD is filling out paper work! I also guarantee without providing the evidence that Houston has fought this!
